Anson lithium offtake deal with LG anchors US brine project

Anson Resources

Anson lithium offtake deal with LG Energy Solution marks a major step for US brine-based lithium supply. Under the Anson lithium offtake deal, LG Energy Solution will purchase 4,000 t/yr of battery-grade lithium carbonate from 2028. This Anson lithium offtake deal secures 40pc of planned nameplate output at the Green River project in Utah’s Paradox Basin.

Offtake secures long-term demand for Green River lithium

The Anson lithium offtake deal gives the Green River brine project a strong anchor customer before construction is complete. Pricing will follow a market-linked formula, aligning contract economics with prevailing battery-grade lithium carbonate prices. As a result, Anson can reduce price risk while still capturing upside in tighter markets.

Meanwhile, the five-year contract, plus an option for another five years, offers rare visibility on future cash flows. LG Energy Solution secures North American lithium carbonate to support its global cell manufacturing footprint. For Anson, this agreement strengthens its bankability as it finalises project financing and engineering.

Fast-track permitting for Green River is reportedly 90pc complete, which should shorten the path to first production. Therefore, the offtake timing from 2028 fits with Anson’s development schedule and gives lenders confidence in future sales volumes.

Korean partnerships deepen technology and market access

The offtake with LG builds on Anson’s earlier link-up with South Korea’s Posco on direct lithium extraction. Under a non-binding agreement, Posco will help build a demonstration plant to test DLE technology at Green River. This Korean axis could give Anson both advanced process technology and long-term market access in Asia.

At the same time, the royalty framework with the Utah government, scaled between 1–5pc, ties state revenues to market conditions. This structure can help align public and private interests through the commodity cycle. If prices strengthen, Utah benefits more, while Anson keeps flexibility during weaker periods.

In strategic terms, Green River’s brine resource adds another US-based option as automakers seek to diversify away from traditional hard-rock supply chains. With LG Energy Solution locked in, the project moves from concept to a credible node in regional battery materials infrastructure.

The Metalnomist Commentary

This offtake shows how mid-tier developers can de-risk brine projects by securing blue-chip battery customers early. If Anson delivers on DLE performance and schedule, Green River could become a template for future US brine developments. However, capex inflation, technology execution and permitting timelines will still determine whether contracted volumes translate into reliable long-term supply.
